Hand tool

Abstract

A prying head is provided in the present disclosure. The prying head, which is used in cooperation with a hand tool, includes a prying portion, a supporting portion and an assembling portion. The prying portion includes a ground-abutting surface and an article-abutting surface. The article-abutting surface is connected to the ground-abutting surface to form a sharp edge. The supporting portion is connected to the prying portion and includes a curved surface. The curved surface is connected to the ground-abutting surface and the article-abutting surface, so as to make an end of the supporting portion away from the sharp edge into a curved form. The assembling portion is connected to the supporting portion and includes a blind hole. The blind hole is recessed from an end of the assembling portion away from the sharp edge.

What is claimed is: 
     
       1. A hand tool assembly, comprising:
 a prying head, comprising:
 a prying portion, comprising:
 a ground-abutting surface; and 
 an article-abutting surface, wherein the article-abutting surface is connected to the ground-abutting surface to form a sharp edge; 
 
 a supporting portion, which is connected to the prying portion, and the supporting portion comprising:
 a curved surface connected to the ground-abutting surface and the article-abutting surface, so as to make an end of the supporting portion away from the sharp edge into a curved form; and 
 a through hole, wherein the through hole penetrates from a first side surface of the supporting portion to a second side surface of the supporting portion opposite to the first side surface; and 
 
 an assembling portion, which is connected to the supporting portion, and the assembling portion comprising:
 a blind hole recessed from an end of the assembling portion away from the sharp edge; and 
 
 
 a wrench head comprising an engaging hole and an engaging end, wherein the engaging end protrudes from a side surface of the wrench head, and the engaging end is detachably engaged with the through hole; and 
 a handle comprising an inserting portion, wherein the inserting portion is detachably engaged with the engaging hole of the wrench head or the blind hole of the prying head; 
 wherein the handle is engaged with the wrench head along an assembling direction, the wrench head comprises a top surface and a bottom surface extending along the assembling direction, a length of a shortest chord of the curved surface of the prying head passing through a center of the through hole is larger than a longest distance between the top surface and the bottom surface, and the longest distance between the top surface and the bottom surface is a width of the wrench head. 
 
     
     
       2. The hand tool assembly of  claim 1 , wherein the ground-abutting surface of the prying head is divided into a sudden-narrowing part and a gradual-narrowing part, the sudden-narrowing part is closer to the sharp edge of the prying head than the gradual-narrowing part, and a narrowing rate between the sudden-narrowing part and the article-abutting surface of the prying head is higher than a narrowing rate between the gradual-narrowing part and the article-abutting surface of the prying head. 
     
     
       3. The hand tool assembly of  claim 1 , wherein a fulcrum is formed at a connection between the curved surface and the ground-abutting surface of the prying head. 
     
     
       4. The hand tool assembly of  claim 1 , wherein the prying head further comprises:
 at least one recessed cavity recessed from a side surface of the prying portion of the prying head. 
 
     
     
       5. The hand tool assembly of  claim 1 , wherein the prying head further comprises:
 at least one through cavity penetrating from a first side surface of the prying portion of the prying head to a second side surface of the prying portion opposite to the first side surface. 
 
     
     
       6. The hand tool assembly of  claim 1 , wherein the prying head further comprises:
 at least one recessed arc recessed from an edge of the article-abutting surface of the prying head.
